Question

Determine x e y para que cada uma das igualdades seja verdadeira:

( x , 2y ) = ( 5 , -8 )

( x , y + 1 ) = ( -2 , 7 )

( 5x , 3y ) = ( -20 , 9 )

( x-2 , y-3 ) = ( -4 , -5 )

( x , y ) = ( 2 , 5 )

( 2x , 3y ) = ( 4 , 9 )

( x , 2y ) = ( 9 , 16 ) 

( 6x , 7y ) = ( 18 , 14 )

( 3x , y ) = ( 21 , 5 )

( x + 1 , y – 2 ) = ( 9 , 6 )

( 7x , 11y ) = ( 21 , 22 )

( 9x , 2y ) = ( 18 , 8 )

( 10x , 3y ) = ( 100 , 6 )

( 3x , 6y ) = ( 75 , 114 )

( 9x , 10y ) = ( 216 , 180 )

( 4x , 6y ) = ( 128 , 204 )

( 6x , 8y ) = ( 294 , 456 )

( 9x , 7y ) = ( 585 , 546 )

( 4x , 8y ) = ( 336 , 768 )

(  10x , 12y ) = ( 410 , 576 )
